Product Application
StiffClip® AL is a versatile, multi-purpose rigid connection for
use in a wide variety of applications. Pre-drilled holes facilitate quick and accurate
fastener placement to structure and/or framing members. Stiffeners in each angle
leg add to overall clip strength. StiffClip AL is tested to resist loads in 3 separate
directions: horizontal, vertical, and lateral (see Load Direction
,for clip orientation). Use of mill-certified steel, combined with tested
load values ensures construction professionals will achieve optimal structural performance.
Material Composition
Steel: ASTM A653/A653M, Grade 50 (340), 50ksi (340MPa) minimum yield strength,
65ksi (450MPa) minimum tensile strength, G-90 (Z275) hot-dipped galvanized coating.
Material thickness: 68mil (14ga, .0713” design thickness).
Allowable load tables incorporate eccentric loading of PAF fasteners. Values with
welded connection may increase.
The attachment of the 1.5” leg of StiffClip AL to other light gauge members
is dependent on screw allowable loads and material composition of the member, and
is to be designed by others.
Note:
- For PAF’s, fasten within ¾” from the angle heel (centerline of the 1½” leg).
- All guide holes do not require fasteners. Number of fasteners used is to be determined
by designer.

StiffClip AL Installation
|
|
Four #12 screws are attached to member through predrilled guide holes in the 3”
leg. Attach short (1.5”) leg to structure/member either utilizing the pre-drilled
guide holes or with weld (attachment through short leg is engineered by others).
If pre-drilled holes are not able to be utilized, follow fastener manufacturer recommendations
for screw placement. |
StiffClip AL Value
- Guide holes for fast and accurate connections
- Stiffeners for additional strength
- Manufactured from mill-certified, 50ksi steel
- No labor spent cutting scrap angle
- Used in a variety of applications
- Extensively tested (reduces liability concerns associated with use of untested,
miscellaneous untraceable material)

Example Details
Loads listed reflect force in a single direction.When multiple loads react on the
connection,it is the responsibility of the designer to check the interaction of
forces.

Load Direction
- Allowable loads are for attachment through 3” leg only. Attachment through
1.5” leg should be engineered. (See material composition on previous page
for calculation purposes.)
- Allowable loads have not been increased for wind, seismic, or other factors.
- Torsional effects are considered on screw group for F3 allowable loads.
